R-Zero is a San Francisco-based smart building technology company that provides a vertically integrated platform for optimizing indoor environments, focusing on energy efficiency, air quality, occupancy insights, and pathogen reduction.[2][5] Originally founded to address pathogen transmission during the COVID-19 era with UV-C disinfection technologies, it now serves commercial, healthcare, government, data center, and office sectors by delivering real-time data on IAQ monitoring, high-efficiency HVAC filtration, space utilization sensors, and occupancy-based controls to cut energy costs, boost productivity, and enhance building health.[1][2][3][4][5] With $161.5M in total funding, including a $105M round, R-Zero demonstrates strong growth, evidenced by recent awards like "Most Disruptive Technology" at Data Center World 2025 and deployments with Fortune 100 firms and healthcare systems.[2][4][5]
R-Zero was founded in the COVID-19 era as the first company built specifically to combat pathogen transmission in indoor spaces, starting with hospital-grade UV-C disinfection technologies and science-backed protocols to make them accessible to businesses.[1] Emerging from this crisis-driven need, it evolved into a broader smart building platform, headquartered at 595 Pacific Ave in San Francisco, with around 204 employees and $41.8M in revenue.[2] Key pivots include expanding from disinfection to IAQ monitors (RESET-certified, launched August 2024), smart HVAC filtration, and occupancy analytics, driven by post-pandemic demands for healthier, efficient buildings; leadership under CEO Jennifer Nuckles has guided this shift, as seen in 2025 award wins for filtration tech.[2][4]
R-Zero rides the wave of smart buildings and sustainability trends, capitalizing on post-COVID emphasis on indoor air quality, hybrid work-driven space optimization, and regulatory pushes for energy efficiency amid rising operational costs.[2][4][5] Timing aligns with aging HVAC infrastructure, AI/data center booms requiring constant cooling, and ESG mandates, where its no-complexity upgrades deliver immediate savings without capex-heavy retrofits.[4] It influences the ecosystem by operationalizing biosafety for public/government sectors and enabling data-driven real estate decisions for enterprises, reducing waste in underutilized offices and healthcare spaces while advancing IoT/building tech standards.[3][5]
R-Zero is positioned for expansion in energy-intensive verticals like data centers and healthcare, with its filtration and IAQ tech set to benefit from tightening global efficiency regs and AI infrastructure growth. Trends like edge computing, net-zero mandates, and advanced occupancy AI will amplify demand for its seamless, sensor-driven optimizations. Expect deeper integrations with BMS/AI platforms and public sector scaling, evolving its influence from crisis responder to essential efficiency enabler—protecting what matters most in smarter, healthier buildings.[4][5]
R-Zero has raised $175.0M across 3 funding rounds. Most recently, it raised $110.0M Series C in February 2023.
